Describe the dataset issue
The necessary attributes formula_terms and standard_name for the hybrid pressure coordinate are missing, so iris cannot read it. The necessary attributes formula_terms and standard_name for the hybrid pressure coordinate are missing, so iris cannot read it. Order of vertical coordinate is reversed, i.e. the derived air_pressure is increasing instead of decreasing. Points and bounds of lev do not match: points: -3.643466 to -992.5561 hPa; bounds : 1-0.9851122 to 0.005031692-0.00225524 hPa. Points and bounds of a and b do not match, one of them is flipped (e.g. b ranges from 1 to 0, while b_bnds ranges from 0 to 1).
